i-pH yelindle
Ixabiso le-pH yelindle linempembelelo enkulu kwimpembelelo ye-flocculants. Ixabiso le-pH yelindle linxulumene nokukhethwa kweentlobo ze-flocculant, umthamo we-flocculants kunye nempembelelo yokuxinana kunye nodaka. Xa ixabiso le-pH li<4, isiphumo sokujiya kwe-coagulation sibi kakhulu. Xa ixabiso le-pH liphakathi kwe-6.5 kunye ne-7.5, isiphumo sokujiya kwe-coagulation singcono. Emva kwexabiso le-pH >8, isiphumo sokujiya kwe-coagulation siba sibi kakhulu kwakhona.
I-alkalinity kwi-liquid inefuthe elithile lokuthintela kwixabiso le-PH. Xa i-alkalinity ye-liquid inganelanga, kufuneka kongezwe ilayimu kunye nezinye iikhemikhali ukuze kongezwe kuyo. Xa ixabiso le-pH lamanzi liphezulu, kuyimfuneko ukongeza i-asidi ukuze kulungiswe ixabiso le-pH libe le-neutral. Ngokwahlukileyo koko, ii-polymer flocculants azichaphazeleki kakhulu yi-pH.
ubushushu bomjelo wamanzi amdaka
Ubushushu bomjelo wamanzi amdaka bunokuchaphazela isantya sokutyibilika kwe-flocculant. Xa umjelo wamanzi uphantsi, i-viscosity yamanzi iphezulu, kwaye inani lokungqubana phakathi kwee-flocculant colloidal particles kunye nee-uncleanness particles emanzini liyancitshiswa, nto leyo ethintela ukunamathelana kwee-floc; ngoko ke, nangona umthamo wee-flocculant unyuswa, ukwakheka kwee-floc kusacotha, kwaye kukhululekile kwaye kucolekile, okwenza kube nzima ukukususa.
ukungcola kwilindle
Ubungakanani obungalinganiyo bee-particles zokungcola kwi-lindle buluncedo kwi-flocculation, ngokuchaseneyo, ii-particles ezincinci nezifanayo ziya kukhokelela kwi-flocculation engalunganga. Uxinzelelo oluphantsi kakhulu lwee-particles zokungcola ludla ngokuba yingozi kwi-coagulation. Ngeli xesha, ukuvuselela i-sediment okanye ukongeza izixhobo zokudibanisa kunokuphucula i-coagulation effect.
Iintlobo ze-flocculants
Ukukhethwa kwe-flocculant kuxhomekeke kakhulu kuhlobo kunye noxinano lwezinto eziqinileyo ezixhonyiweyo kwi-lindle. Ukuba izinto eziqinileyo ezixhonyiweyo kwi-lindle zifana ne-gel, ii-flocculants ezingaphiliyo kufuneka zikhethwe ukuze zingasebenzi kakuhle kwaye zijiye. Ukuba ii-floc zincinci, ii-polymer flocculants kufuneka zongezwe okanye kusetyenziswe izixhobo zokujiya ezifana ne-activated silica gel.
Kwiimeko ezininzi, ukusetyenziswa okudibeneyo kwee-flocculants ezingaphiliyo kunye nee-polymer flocculants kunokuphucula kakhulu isiphumo sokujiya kunye nokwandisa ububanzi bokusetyenziswa.
Idosi ye-flocculant
Xa usebenzisa i-coagulation ukunyanga nawaphi na amanzi amdaka, kukho ii-flocculants ezilungileyo kunye ne-dosage engcono, edla ngokugqitywa kuvavanyo. I-dosage egqithisileyo inokubangela ukuzinza kwakhona kwe-colloid.
Ulandelelwano lwedosi ye-flocculant
Xa kusetyenziswa ii-flocculants ezininzi, ulandelelwano olufanelekileyo lokulinganisa kufuneka luchongwe ngokusebenzisa iimvavanyo. Ngokubanzi, xa kusetyenziswa ii-flocculants ezingaphiliyo kunye nee-flocculants eziphilayo kunye, kufuneka kongezwe ii-flocculants ezingaphiliyo kuqala, kuze kongezwe ii-flocculants eziphilayo.
